SIDE EFFECTS

Clinical Studies Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety data reflect exposure to Endometrin (progesterone) in 808 infertile women (74.9% White, 10.3% Hispanic, 5.4% Black, 5% Asian, and 4.6% Other) in a single Assisted Reproductive Technology 10 week clinical study conducted in the U.S. Endometrin (progesterone) was studied at doses of 100 mg twice daily and 100 mg three times daily. The adverse reactions that occurred at a rate greater than or equal to 2% in either Endometrin (progesterone) group are summarized in Table 1.

DRUG INTERACTIONS

No formal drug-drug interaction studies have been conducted for Endometrin (progesterone) . Drugs known to induce the hepatic cytochrome-P450-3A4 system (such as rifampin, carbamazepine) may increase the elimination of progesterone. The effect of concomitant vaginal products on the exposure of progesterone from Endometrin (progesterone) has not been assessed. Endometrin (progesterone) is not recommended for use with other vaginal products (such as antifungal products) as this may alter progesterone release and absorption from the vaginal insert [see WARNINGS and PRECAUTIONS].

PRECAUTIONS

Cardiovascular or Cerebrovascular Disorders

The physician should be alert to earliest signs of myocardial infarction, cerebrovascular disorders, arterial or venous thromboembolism (venous thromboembolism or pulmonary embolism), thrombophlebitis, or retinal thrombosis. Endometrin (progesterone) should be discontinued if any of these are suspected.

Depression

Patients with a history of depression need to be closely observed. Consider discontinuation if symptoms worsen.

Use of Other Vaginal Products

Endometrin (progesterone) is not recommended for use with other vaginal products (such as antifungal products) as this may alter progesterone release and absorption from the vaginal insert [see DRUG INTERACTIONS].

Patient Counseling Information

Use In Specific Populations

Pregnancy

Endometrin (progesterone) has been used to support embryo implantation and maintain clinical pregnancy in one clinical study. The livebirth outcomes of these pregnancies were as follows:

  • Among the 404 subjects treated with Endometrin (progesterone) twice daily, 143 subjects had livebirths consisting of 85 singletons, 56 twins, and 2 triplets. In this treatment group, 13 subjects had a spontaneous abortion, 1 subject had an ectopic pregnancy, and 7 subjects reported fetal birth defects (3.4% based on 203 livebirths).
  • Among the 404 subjects treated with Endometrin (progesterone) three times daily, 155 subjects had livebirths consisting of 91 singletons, 60 twins, and 4 triplets. In this treatment group, 22 subjects had a spontaneous abortion, 4 subjects had an ectopic pregnancy, and 7 subjects reported fetal birth defects (3.1% based on 223 livebirths).

Birth defects reported in the Endometrin (progesterone) twice daily group included: one fetus with a cleft palate and intrauterine growth retardation, one fetus with spina bifida, three fetuses with congenital heart defects, one fetus with an umbilical hernia, and one fetus with an intestinal anomaly.

Birth defects reported in the Endometrin (progesterone) three times daily group included: one fetus with an esophageal fistula, one fetus with hypospadias and an underdeveloped right ear, one fetus with Down's and an atrial septal defect, one fetus with congenital heart anomalies, one fetus with DiGeorge's syndrome, one fetus with a hand deformity, and one fetus with cleft palate.

CLINICAL PHARMACOLOGY

Mechanism of Action

Progesterone is a naturally occurring steroid that is secreted by the ovary, placenta, and adrenal gland. In the presence of adequate estrogen, progesterone transforms a proliferative endometrium into a secretory endometrium. Progesterone is necessary to increase endometrial receptivity for implantation of an embryo. Once an embryo is implanted, progesterone acts to maintain a pregnancy.

Pharmacokinetics

Absorption

Progesterone serum concentrations increased following the administration of the Endometrin (progesterone) Vaginal Insert in 12 healthy pre-menopausal females. On single dosing, the mean Cmax was 17.0 ng/mL in the Endometrin (progesterone) twice daily group and 19.8 ng/mL in the Endometrin (progesterone) three times daily group. On multiple dosing, steady-state concentrations were attained within approximately 1 day after initiation of treatment with Endometrin (progesterone) . Both Endometrin (progesterone) regimens provided average serum concentrations of progesterone exceeding 10 ng/mL on Day 5. The pharmacokinetic results are summarized in Table 2.

Distribution

Progesterone is approximately 96 % to 99 % bound to serum proteins, primarily to serum albumin and corticosteroid binding globulin.

Metabolism

Progesterone is metabolized primarily by the liver largely to pregnanediols and pregnanolones. Pregnanediols and pregnanolones are conjugated in the liver to glucuronide and sulfate metabolites. Progesterone metabolites that are excreted in the bile may be deconjugated and may be further metabolized in the gut via reduction, dehydroxylation, and epimerization.

Excretion

Progesterone undergoes renal and biliary elimination. Following injection of labeled progesterone, 50-60% of the excretion of metabolites occurs via the kidney; approximately 10% occurs via the bile and feces. Overall recovery of the labeled material accounts for 70% of an administered dose. Only a small portion of unchanged progesterone is excreted in the bile.

Clinical Studies

Luteal Supplementation During Assisted Reproductive Treatment Study

A randomized, open-label, active-controlled study evaluated the efficacy of 10 weeks of treatment with two different daily dosing regimens of Endometrin (progesterone) (100 mg twice daily and 100 mg three times daily) for support of implantation and early pregnancy in infertile women participating in an Assisted Reproductive Technology treatment program. Efficacy was assessed on the endpoint of ongoing pregnancies, defined as the presence of at least one fetal heartbeat seen on ultrasound at 6 weeks post-embryo transfer. The study randomized to Endometrin (progesterone) 808 infertile women (74.9% White; 10.3% Hispanic, 5.4% Black, 5 % Asian, and 4.6% Other) between 19 and 42 years of age (mean age 33) who had a body mass index < 34 kg/m² at screening.

The ongoing pregnancy rates for subjects treated with both dosing regimens of Endometrin (progesterone) were non-inferior (lower bounds of the 95% confidence interval of the difference between Endometrin (progesterone) and the active comparator excluded a difference greater than 10%) to the ongoing pregnancy rate for subjects treated with the active comparator. The results of this study are shown in Table 3.

*Ongoing pregnancy defined as the presence of at least one fetal heartbeat seen on ultrasound at 6 weeks post-embryo transfer.

Subjects participating in the study were stratified at randomization by age and ovarian reserve (as measured by serum FSH levels). The ongoing pregnancy rates for these subgroups are shown in Table 4.

Pregnancy rate percentage difference between Endometrin and comparator -12.2% -7.7%
95% Confidence Interval for difference vs. comparator [-31.0, 7.7] [-26.6, 11.6]

In subjects under the age of 35 or with serum FSH levels less than 10 IU/L, results from both dosing regimens were non-inferior to the results from the comparator with respect to ongoing pregnancy rates. In women age 35 and older and in women with serum FSH levels between 10 and 15 IU/L, the results with respect to ongoing pregnancy rate for both dosing regimens of Endometrin (progesterone) did not reach the criteria for non-inferiority.

Subjects who became pregnant received study medication for a total of 10 weeks. Patients over 34 kg/m² were not studied. The efficacy of Endometrin (progesterone) in this patient group is unknown.

What is progesterone vaginal (Endometrin)?

Progesterone is a female hormone important for ovulation and menstruation. Progesterone causes changes in the lining of your uterus, making it easier for a fertilized egg to attach to the uterus at the beginning of pregnancy. Progesterone then helps your body maintain the pregnancy.

Progesterone vaginal is used in fertility treatment as part of Assisted Reproductive Technology (ART) for women unable to get pregnant due to a lack of natural progesterone in the body.

Progesterone vaginal is also used to cause menstrual periods in women who have not yet reached menopause but are not having periods due to a lack of progesterone in the body.
